Event Focus

Why does an astronaut wear a spacesuit?



This module may be presented as a video conference AND web conference presentation (Skype or Conference Me)


If your friend were to ask you, “What is a spacesuit?” or “Why do astronauts have to wear special suits in space?” what you would tell them? NASA has spent decades meeting milestones in its quest for space exploration. One of these milestones was creating the ability for astronauts to conduct space walks. In order for astronauts to safely conduct a space walk, they must be well protected from the dangers of outer space. This module allows students to discover what a space suit is and why it is essential for astronauts to wear them in space.


Instructional Objectives




Learners will share what they know about space and why astronauts need protection in space



Learners will observe the characteristics of outer space and understand the importance of wearing a spacesuit in space



Learners will identify the parts of the spacesuit



Learners will discover the region of the body each part of the spacesuit belongs to and how it protects that region of the body



Learners will demonstrate what they have learned by completing a post-conference assessment activity.


Sequence of Events


Pre-Conference Activities


Students will complete a pre-conference assessment about space.

Students should bring in the following items to correspond the parts of the spacesuit:

o     Headphones

o     Sunglasses

o     Shirt

o     Pants

o     Gloves

o     Shoes

Astronaut- a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft s a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft


Oxygen- colorless, odorless, tasteless gaseous chemical element, which appears in great abundance on Earth; without oxygen, most organisms will die within minutes


Spacesuit- A fully equipped spacesuit is really a one-person spacecraft. The formal name for the spacesuit used on the space shuttle and International Space Station is the Extravehicular Mobility Unit, or EMU. "Extravehicular" means outside of the vehicle or spacecraft. "Mobility" means that the astronaut can move around in the suit. The spacesuit protects the astronaut from the dangers of being outside in space


Temperature- The degree or intensity of heat present in a substance or object


Videoconference Activities


Students will learn about spacesuits as a NASA coordinator demonstrates the parts of the spacesuit, explains why spacesuits are important for space exploration, and connects science concepts to real-world experiences.

This event will result in an interactive activity involving Leo the Lion where students will go through each part of the spacesuit.


Post-Conference Activities


As part of the post-lesson activity, students will construct a chapter that can be included in their “My Big Book About Space” book.
